A pocket 23 is providedin the last in substantial axial alignment with the holes sole, wherebythis construction makes it possible to set the jack-post in properposition to bring the bore through the heel into axial registration withthe opening of the clamping bar 29 for final securement of the heel tothe shoe. Also mounted in the dovetail track 6 is a carrier securable inadjusted position as by the 'set screw 4|, said carrier having anupwardly extending bracket arm 42 preferably slotted to adjustablyreceive the bolt 43 by which a com panion bracket arm 44, carrying a'toe rest at its upper extremity, may be adjusted as to height above thebase plate, said toe rest being preferably curved or of U shape toreceive therein and steady the toe portion of the shoe during the heelsecuring operation. The adjustability of this toe rest is providedbecause of the different styles of shoes handled by this mechanism.

In Figs. 5 and 6 are shown one form of modified heel clamping bar,wherein the bar has trunnion ends such as 5| rotatable or rockable inbores provided in the upper ends of the slidable rods 21 and 28, theultimate position of the bar 50 being 'adjustably secured by set screwssuch as 52. The central portion of this bar is provided with a groove orcut-away surface portion 53 for engagement with the surface of the heel,but the surface of this groove may be formed parallel to a face of thebar since the latter may be rocked or turned, through its trunnionengagement with the rods 21 and 28, to bring said surface into the planeof the heel, Fig. -6 showing in dotted lines an adjusted position ofsaid bar. Obviously other modifications of the adjustability of thiscross bar may be had including the omission of the set screws 52 butproviding the surface of the ends 5| of said bar with longitudinallyextending ridges or teeth adapted to engage correspondingly formedridges or teeth on the inner surface of the upper ends of the rods 2!and 28, this construction permitting adjustability in predeterminedpositions whereas the set screws '52 and smooth surfaces of the trunnionbearings shown in Fig. 5 permit any adjustability desired.

The method of securing the heel to the shoe is as follows. Upon the lastI is laid the necessary sole layers such as l5 and I6 with the openingstherein in registry with the pocket 23 of the last, and the short screw22 with its associated counter-sunk washer disc interposed between thelayer l5 and the bottom of the last, said short screw dropping bygravity into said pocket, it

being understood that the last will be -in inverted position as shown inFig. 2. The last with the sole layers may then be subjected to theoperations of the lasting machine, sole laying, levelling, andsubsequently to the welt machine, and trimming machine during thefurther buildingup of the shoe structure, Without interference from theshort screw because the latter by virtue-of the pocket 23 is permittedto 'occupy such a position as to prevent it from extending upwardly intothe way of the machine parts.

The shoe, still on the last I, is then taken :to the heeling room wherethe heel is applied 'to the shoe. The heel naturally has been providedwith the bore [8 and just previously to placing the heel on the shoe theusual coat of glue is applied to the surface of the sole and to the heelseat, the glue being permittedto enter the enlarged portion of the boreadjacent the heel seat. The connector 2| is then screwed onto the end ofthe short screw 22 until'the latter has been worked upwardly out of thepocket 23 with the head of the screw contacting the counter-sunk portionof the disc washer. The outer surface of the connector is roughened, asby grooves shown in Fig. 2, so that when it ultimately is passed intothe enlarged end of the 5 bore I8, the glue therein will enter saidgrooves and, upon drying, tend to key and anchor said connector in finalposition.

The heel is then applied to the shoe with the connector entering theportion of the bore pro- 10 then operates the lever or foot pedal tomove 15 the heel clamping bar 29 downwardly upon the heel and, while thepressure of said clamping bar is still upon'the heel, a screw driver orother suitable tool is passed through the opening 30 of the bar andoperated to thread the long screw 20 into the connector 2| topermanently secure the heel to the shoe, the head of the long screwultimately coming into seated position on the metallic washer [9. Thepressure of the clamping bar may then be released and, after the glued25 joint has hardened, the usual top lift not shown may be applied tothe bottom of the heel to cover the head of the screw 20.

From the foregoing description it Will thus be seen that by thisinvention there is provided a means for, as well as a method of,securing a heel to a shoe. The screws 26 and 22 together with theconnector 2| constitute tensioning members for fastening the heel to thesole. The jack-post 4 together with the last I and the clamping bar '29constitutes a means for applying pressure to the heel while it ispositioned upon the sole; thus making it possible to lock the members20, 2| and 23 under tension while the pressure is applied. Lastly byproviding the pocket 23 in the last it is possible to apply the shortscrew 22 to the sole portion of the shoe and to perform the necessaryoperations upon the sole portion without interference from said screw.

It is obvious that those skilled in the art may'i5 vary the details ofconstruction and arrangements of parts constituting the apparatus, aswell as vary the steps and combinations of steps constituting themethod, without departing from the spirit of this invention, andtherefore it istso not desired to be limited to the foregoing disclosureexcept as may be demanded by the claims.

What is claimed is: 1. The method of securing a heel to the sole of ashoewhich consists in positioning the heel on the sole; applyingpressure to the combined heel and'sole; and securing the heel and solewhile the pressure is so applied, by independent tension applied'throughthe base of the heel.

2. The method of securing a heel to the sole of '60 ashoe by a pluralityof tensioning members which consists in applying one of the members tothe sole .portion of the shoe in such manner as to permit readyoperations upon the sole portion'during the building-up of the shoe andapplyinga second member to the first member after the shoe is built up;applying a third member to the heel and second member and positioningthe heel on the sole; applying pressure to-the combined heel and v sole;and securing all of the members while the pressure is so applied, byindependent tension applied through the base of the heel.
